A game of shark and ray: Rays act differently when sharks are around

As our oceans change, we don’t really know what the current decline of sharks means for stingrays, or for the coral reefs where they both live. Scientists at James Cook University and the Australian Institute of Marine Science want to find out. Kristin HuizengaI am a PhD student studying Biological Oceanography at the University of […]

Tracking predators in seagrass beds

Scientists have long recognized that predators are more abundant at lower compared to higher latitudes. Read more to find out how a group of marine ecologists investigated the importance of predator-prey interactions in seagrass beds. Katherine BarrettKate is a 4th year PhD candidate in the Biological Sciences Department at the University of Notre Dame, and […]

Orca vs Narwhal

Orcas are natural predators of narwhals, but they are seasonally kept at bay by Arctic sea ice. As the Arctic becomes increasingly ice-free, killer whales are arriving earlier and hanging out longer in narwhal habitat. How do narwhals fare? Read more to find out! Megan ChenI graduated with a Masters of Coastal & Marine Management […]

It’s Getting Hot In Here: How Ocean Acidification and Warming Affect Shark Hunting and Behavior

Elasmobranchs such as sharks and rays face physiological and behavioral changes due to ocean acidification and rising ocean temperatures. Read about how these changes influence how sharks hunt and their role in the marine ecosystem. Aditi TripathyHello! I received my B.S. Marine Biology with a minor in Acoustics at the University of Rhode Island. Currently, […]

Are Fisheries Scientists Ringing the Dinner Bell for Marine Mammals?

Acoustic telemetry is a valuable technique used by fisheries scientists to track fish movements. However, a new study suggests that these anthropogenic signals may make tagged fish an easy target for marine mammal predators like dolphins and seals. Derrick AlcottDerrick is pursuing a Ph.D. in the Organismic and Evolutionary Biology Program at the University of […]

Two Crabs and an Alga- a story of protection and evolution.

Tiny mud crabs try to escape big blue crab predators but without the help of evolution to guide shelter choices what will they do? Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue crab in the Gulf of […]

Making the best of a bad situation: the upside of squid injury.

Injured squid are more vulnerable to attack from predators but stepping up their defensive behaviors gives them a fighting chance. Long term pain sensitivity makes this possible. Sarah GiltzI am a doctoral candidate in Ecology and Evolutionary Biology at Tulane University. My research focuses on the larval dispersal and development of the blue crab in […]
